Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered in REDAXO CMS 4.7.2. There is a CSRF vulnerability that can add an administrator account via index.php?page=user.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A Cross-Site Request Forgery (CSRF) vulnerability in REDAXO CMS 4.7.2 allows unauthenticated attackers to trick authenticated administrators into creating new administrator accounts by submitting a malicious form to index.php?page=user. The affected endpoint lacks anti-CSRF token validation, enabling unauthorized account creation.

MitigationImplement anti-CSRF tokens on all state-changing operations in the user management interface, specifically the user creation form at index.php?page=user, and validate these tokens server-side before processing account creation requests.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Redaxo CMS version
    Locate the version file or admin panel footer that displays the installed Redaxo CMS version number
    Affected if The installed version is exactly 4.7.2 (no other versions are affected per the provided range)
  2. Verify user management module exists
    Access the admin interface and navigate to index.php?page=user or locate the user creation form in the CMS installation
    Affected if The user management page at index.php?page=user is accessible and functional in the CMS
  3. Inspect user creation form for CSRF token
    View the HTML source of the user creation form at index.php?page=user and search for a hidden input field containing a token value (commonly named 'csrf_token', 'token', 'rex_csrf_token', or similar)
    Affected if The form lacks a hidden CSRF token field or the token field is present but not validated server-side before processing account creation

A user is affected if they are running Redaxo CMS version 4.7.2 and the administrator user creation form at index.php?page=user does not implement CSRF token protection.
